Xamarin.iOS App - TestFlight Build Crashing without Logging Anything - ios

I have been using TestFlight for several months now to distribute new builds to our beta testers and for the most part I haven't had any problems. As of yesterday (4/11/2017) however, the app is crashing immediately after launch on all of our test devices - without generating any crash reports, so I have no idea how to identify the problem.
I thought that the issue may have been related to using HockeyApp for crash logging (although I have been using that for weeks without any problems), but after removing the related code the crashes are still occurring.
The app runs fine in the simulator, and runs fine on all of our test devices if installed directly through Xamarin Studio (both debug and release versions are working). These crashes are only occurring installing the app through TestFlight. Can anyone offer any suggestions as to how I can track this problem down?

App crashes on App Store but works in TestFlight

I have just release an app to the App Store.
I have tested the build using TestFlight and everything worked.
After installing it from App Store it crashes upon opening.
Switching back to the same build but installed through TestFlight makes it work once again.
Does anyone know of any difference between a TestFlight version and an App Store version (of the same build), or have experienced anything similar?
The issue appears to be network related (I think, but I have very little information, and can’t setup a test env as it only happened after releasing to the App Store) and the issue is reproducible on multiple devices.
The app is a React Native (Expo build with EAS) and the source in its entirety can be found at https://github.com/pictoroma/app/
Edit: added source url
Resubmitted another build using the same source, and now everything works. Maybe something inside Apple’s pipeline corrupted the binary between TestFlight and App Store 🤷

React Native iOS app different code on simulator vs ad hoc/App Store

I have been working on a React Native app for several weeks. I recently pushed a version to TestFlight. When I started getting feedback from users I noticed that their screenshots were different than the latest changes I made. They were from older revisions.
I ran the app in the iOS Simulator. I get the correct version of the code.
I ran the app on a device connected to my Mac. I get the correct version of the code.
I ran the app distributed ad hoc and I get an older version of the app.
I haven't seen anything like this before and baffled as to what could cause the problem.
I connected with Brent Vatne on Expo's Slack. I forgot to run expo publish before running the release build.

IOS app crashes after launch with testflight

I have seen a few similar questions but nothing to help me resolve my issue.
My app works when built in debug mode. It works via testflight on devices running iOS 11+. We support iOS 9 and above, so when i get the app via testflight on an app running iOS 9 the app instantly crashes. I find it unusual that this would run fine on a newer version of the OS but fail on the older version.
I understand that this is a pretty broad question. I presumed it would be an issue with certificates but if that was the case i would expect to see the same issue on each OS version. I have compiled the app for release and ran it on a device to replicate the issue which it does. In the device logs i can see the error.
Attempt to add an app with insufficient id, info
Again i understand i haven't been able to give much information on this error, but i am hoping someone has been in a similar situation and can give me some pointers.

Xamarin.iOS App crashes after showing launch screen when distributed through TestFlight

I'm currently working on an Application using Xamarin.iOS framework. The App runs as expected when I run it on Simulator & in iPhone using debug configuration. But, when the App is uploaded to TestFlight using a Distribution Profile, it crashes immediately after showing the Splash Screen for a second. My TestFlight users have repeatedly reported that it crashes only on TestFlight builds. Not sure why this happens?
When the build is distributed using Ad-Hoc profile, it works fine as it should.
I have tried updating MacOS, Xamarin Studio, XCode, but in vain.
Any ideas would be appreciated.

App crashes at startup

Alright, my app is working great in the simulator, but when I transfer the app to my iPhone it crashes at startup. I am installing the app via cydia. The app can be installed via this source chrisrjones.com/repo The crash report can be found here - > crash report The source code for the app can be found here -> https://github.com/ipatch/KegCop
I created a shell script to code sign and build the deb package for the app, and have not had any problems with the app so far. I have no idea what I am looking for in the crash report, as I haven't really done much looking at these things. Also I am pretty sure this isn't a code sign bug, but I could be wrong. The app launches for a second or two then crashes, I am pretty sure the code sign crash happens quicker than what I am experiencing.
I am using Xcode 4.3.2 on OS X 10.7.4, iOS version is 5.1.1 I am using ARC in my Xcode project.
Any thoughts?
Alright, to fix this problem, I deleted the Accounts.sqlite file located at /var/mobile/Library/KegCop/ I then removed the app via Cydia. I restarted the phone. I reinstalled app via Cydia, then the app quit crashing. (yay)
